    When you have raw unburnt fuel coming out exhaust it’s a white cloud looks like stream.

    The knocking you hear is fuel knock because that one cylinder is not able to ignite that amount of fuel so it gives a knocking sound.

    The leak what looks like a oil leak is the raw fuel and soot being mixed together giving the impression it’s oil.

    I have seen this happen numerous times on big and small Diesel engines.

    The VGT going down has nothing to do with the injector problem just coincidence

    Great advice above, I am thinking the next step would be to plug off fuel lines one at a time to figure out which injector or cylinder has the issue.

    Just talked to my injector guy.

    I'm going to remove all the injectors and send them in for a bench test and go from there.

    Can't wait to get this beast running so i can update you all with a good start and a drive.

    The 467 already sounds great if it wasn't for the knock haha.
